Why is the effect of mobile Signal Jammer on mobile 5g relatively poor?
The interference effect of the mobile phone signal jammer on the mobile 5G is tested at the on-site meeting room at the request of the customer. It is found that the interference effect of the mobile phone signal jammer is worse than that of the 234G.
1. In the mobile signal jammer, the mobile 5g uses the 2600mhz frequency band, which interferes with the mobile 4G before 5g. After 5g is put into operation, China Mobile will expand the capacity of this frequency band for 5g.
2. The mobile phone signal jammer before 2600mhz uses the frequency band of 2555-2655mhz. It can be concluded that a module covers 100m bandwidth to shield 4G. After 5g was officially put into use, China Mobile expanded this frequency band to 160m, that is, 2515-2675mhz frequency band. After expanding the bandwidth, a module was used to interfere with 5g. Since the power of a single module is equal, the interference effect will be weakened when the interference effect is narrow relative to the bandwidth after expanding the bandwidth. Under the same power, the wider the bandwidth, the weaker the interference effect; The narrower the bandwidth, the better the interference effect. Therefore, if you want to increase the interference effect, you need to split this frequency band.
3. In order to improve the interference effect of 5g, it is necessary to add 2600mhz module to the mobile phone signal jammer, and at least add two same modules. Specifically, it can be divided into three frequency bands, 2515-2569mhz, 2569-2623mhz and 2623-2675mhz respectively, so as to reduce the interference bandwidth and increase the interference effect. However, after the split, many people have doubts about whether a mobile phone signal jammer can be accommodated after adding the output module. There is no need to worry about this. The mobile phone signal jammer produced by Nanjing Baikang Electromechanical Technology Co., Ltd. has considered this problem at the beginning of design. In the structural design, it can support 24 channel output at the same time, which has full space to realize.
